Influence of boundary conditions on the mechanical testing of orthopaedic devices
Résumé
Sample stiffness construct is often measured in studies relating to the mechanical behaviour of bone with/without implant. To improve the fit of the sample in the testing machine, and hence the reproducibility, researchers embed samples at their extremities in resin, in particular PolyMethyl MethAcrylate (PMMA)1. The aim of this work was to study the influence of resin-based embeddings on the total stiffness of the experimental setup of implanted tibiae used for fracture reduction research.
